Abstract
From yellow petals of Blue Mahoe, besides the known flavonoids gossypetin and gossypitrin, a new one gossypetin derivative was isolated from ethanolic extracts after Soxhlet extraction. Hence, in this study, we present a validated, sensitive and reliable NMR method for the simultaneous identification of flavonoids in this flower drug. Structure analyses of this flavonoid, revealed the identical glycoside moiety attached to a flavonol skeleton like gossypitrin, for which the structure of gossypetin-3'- O - β -glucoside was deduced from extensive NMR experiments.
